Abstract

1330870 Treating gases with liquids BRAXTON CORP 9 Dec 1970 [10 Dec 1969] 58507/ 70 Headings B1R and BIT Solid particles, e.g. fly ash, are removed from a gas by first passing the gas feed 20 into a saturator chamber 26 wherein it is saturated with water vapour from sprays 28 controlled by humidity sensors 33, then passing the gas stream through an expansion turbine 40 wherein the gas is expanded causing the formation of secondary particles of water by condensation of the water vapour, next passing the gas stream into a sonic agglomeration chamber 50 wherein it is exposed to a sonic field which causes the suspended molecules or solids and water to vibrate and agglomerate into composite particles, and finally removing the composite particles in cyclone 52. A compressor 60 mechanically coupled to turbine 40 is connected upstream of cyclone 52. Chamber 50 is provided with a drain 44 discharging through pump 46. If the gas stream contains, in addition of solid particles, undesired gaseous components, e.g. sulphur dioxide, then these may be removed by introducing a suitable reactant, e.g. ammonia, into the gas stream at 39 by valve 37.
